Title: Rock drill diamond and carbide cutting tip arrangement - has different cutting zones to ensure fine grinding of cut material
Inventor: GARNER LLOYD LYLE
IPC: E21B10/48
Filed: 1976-12-08
Abstract: A rock drill has three equally spaced roller cutters (41) with their axes of rotation sloping towards the middle and ahead of the cutting head. Each cutter has rings of carbide cutting tips (42) and the dia. of the head (40) is greater than the dia. of the path of the outermost rings of carbide tips. This leaves room for sets of diamond cutters (43) rotating around a circular path which also has a greater dia. than that of the outermost carbide tips. Between each pair of roller cutters is a hole (44) for discharge of drilling fluid. Alternative cutting tip arrangements are designed so that material cut by the diamond tip is ground up finely by the carbide tips.

Title: Exercise frame for strengthening arm and shoulders - has head rest and handles attached to horizontally hinged triangle
Inventor: KUELKENS FRANZ
IPC: A63B21/055
Filed: 1976-12-14
Abstract: Training and exercise equipment which is used to strengthen arm and shoulder muscles, consists of a frame that is hinged about a horizontal pivot (9). One corner of the triangular frame (10) is attached to a spring loaded cable (8) whilst the third corner carries a fork shaped head rest (11-13) and two sets of handles.

Title: RF microstrip line with curved recess in substrate - is designed to keep impedance constant by gradually reducing line thickness
Inventor: SCHILZ WOLFRAM DIPL PHYS DR
IPC: H01P3/08
